@Oleg: Maybe the Dandelion chip has been improved since I had mine. I am not aware that it was possible to disable the annoying feature of not being able to shoot unless the adapter sensed correct focus when I had one. Additionally, focus adjustment was not available to the best of my knowledge.
There only exists a single programmable version of the Dandeloin chip; the older ones are non-programmable. My bet is your problems are related to the lack of programming instructions. Here you go: http://filmprocess.ru/oduvanchik/instructions/programming_en.html
Disabling the focus catch feature is the first, adjusting AF confirmation point is the second step I always perform on my adapters. The most tricky part is actually entering the programming mode (you have to unmount the lens, mount it again and take a 13-second exposure within a 3-second interval after mounting it; better to use AI Servo on the camera, or the focus catch feature will prevent you from taking an exposure). From there, it's all easy, and you can use the DoF preview button instead of taking exposures to program it.
Well done everyone on the autumn colours. Wow! The Oly 24 seems a nice little lens to own!
I hope I get some time to excercise my Oly's in the coming weeks. It is, indeed, autumn, however we seem to lack the really great colours I see you guys presenting. Just wow.
blackbird: your focus seems rather continously off. is that by design (eg you like them that way) or because you haven't got a focussing screen optimized for manual focussing yet?
I'm sure they would have had them in development, maybe they were never happy with their IQ.
So far I'm liking my new 35/2 OM, I just have to use it more.
seen by Olympus OM Zuiko Auto-S 1.4/50
This Zuiko provides a hit and run easy focus due to its sharpness and contrast even when used open wide. Wald von praktinafan auf Flickr

Hi Harro. Thanks for noticing. Yes, actually I do not intend to get the photos OOF, but because street photography requires quick reflexes, it is pretty difficult to MF. Also, I don't have a manual focus screen, so it is difficult to focus. Having a 20d and its small viewfinder doesn't help either. Well, i can't do any better with the gear because I'm still a couple of years away from graduating, so I'll have to get better with technique and composition.
I guess I should consider getting a focusing screen. Does anyone have a suggestion as to which one? Is it difficult to do? I don't know why they are so expensive! Besides, they are only a piece of plastic, right?
I agree, my OOF problem keeps ruining great shots. Like I personally thought these two would be great if they were in focus.

why does the photo have to be perfectly focused? I think your shots are fine as is.
Tons of my shots are motion blurred, out of focus, a touch lop sided or something like that. Maybe it will stop someone else from liking my photos, but it doesnt stop me from liking them. Just my 2c
Oh and I was using the cam2_usa adapter with AF Confirm. It was pretty darn accurate.
Here is some Autumn color from an OM Zuiko 35-70mm f/4.
I haven't seen too many photos here from this version of Olympus' standard zoom. There is much more interest in the f/3.6 version, but I think this was the best $25 I ever spent on a lens.
Finally a word about my adapter. There has been some discussion about adapters, lately. I am using a big_is EMF-chipped adapter on this lens. As Oleg mentioned, and I have found this to be true, there is an issue with overexposure using that adapter when setting it to report the f-stop used to EXIF. Until today, I got around that issue primarily by using exposure compensation – a solution I was not entirely happy with. This morning, I believe I solved that problem. There are two methods of metering with the EMF chip when reporting f-stop to EXIF. When I used the first method described in the EMF chip manual I had overexposure issues but this morning when I tried using the second method described in the EMF user manual I was able to get good results. The test shot below is metered using aperture priority pattern metering with no exposure compensation on a 5D Mark II and is straight out of the camera with no adjustments of any kind except to convert to jpeg. It is only a test shot with no redeeming photographic qualities but I am happy with the exposure. http://www.pbase.com/rtallent/image/129591134/original.jpg
